If you need to control numbers, the biologist will tell you to go ahead and take the doe first chance you get. Most people on here will tell you to shoot them too. Personally I try to take dry does first and hold off taking nursing/mother does until later on (even into January if possible). My order is something like dry, 1 large fawn, 2 large fawns, 1 smaller fawn, 2 smaller fawns. We raise livestock too and I can tell you that there is no substitution for allowing that animal to get the best start in life possible. I saw a doe nurse her twins two weeks ago so you can't tell me that they've all been weaned. I do realize that if the doe has already bred then you are sort of wasting your bucks' efforts, but I'm not sure there's a good solution.
